Toallwhomz'tmay concem:

Be it knownthat I, HARRY R. Rnnroms', a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Shaft-Hanger Bearings, of which the following is aspecification.

My present invention relates to shaft bearings and aims to provide a relatively simple and eflicient form of shaft hanger hearing which to a-certain extent will be self-adjustin and which will be entirely practical an desirable in other respects.

Briefly theinvention comprises the combination-with the hanger box and the shaft, of a race ring or rings'loosely engaged .on the shaft cooperating with a corresponding mounted in .the box and an abutment co lar 'or collars fixedly engaged on the shaft to limit the. longitudinal movement of the inner. race ring or rings and having keying shoulders interlocking or rings longitudinally of the shaft in suc a way as to permit the desired limited self-ad'ustment of the parts.

Other features of t e invention will api pearas the specification proceeds.

- illustrated the invention embodie In the accompanying drawin I have in difierent ractical forms, but with the understan ing however that other modifications may be made to suit requirements without departure from the true spirit and scope of the invention.

In said drawing Figure 1, is a longitudinal sectional view of a double row bearing with the shaft shown broken awa at its op osite ends.

Fig. 2, is a simi ar view 0 a single row bearing.

Figs. 3 and 4 are perspective views of one of the inner race rings and one of the abutment collars used in the first form of theinvention.

Referring to the various parts in detail,

.5 designates the hanger box constructed to fit the usual hanger bracket and provided in this. disclosure with annular seats 6 in its opposite end rtions to receive the-outer race rings 7. ese outer race rings may be secured in lace in various ways as by means of thev ust rings S-which are shown race ring a unit, the box 1n its entirety simply being slid alongthe shaft to the position-where it will properly fitin the hanger bracket.

After the proper relative adjustment of the hanger box and shaft is effected, the.

inner race rings are secured in said long'i-' 1 tudinally adjusted position on the shaft and are keyed against rotary movement on the shaft by means of abutment collars 13 which are secured fast to the shaft at the ends of the inner race rin asby means of set screws 14. These a utment collars, by pro- -viding abutments for the inner race rings,

prevent longitudinal shifting of the box and shaft and the keying of the race rings on the shaft 3 is efiected in this particular disclosure by providing the abutment collars with lugs 15 pro'ecting lon itudinally from the abutment en of the co lar into engagement with the longitudinal notches 16 in the abutment face of the .inner race rin This construction, it will be app rent will allow for a certain amount of longitudinal moveout unkeying the ring from'the shaft. The parts may be set u with a slight space intervening between t e'abutanent faces of the inner race rings and adjoining abutment collars as indicated at 17, so as-to osit'ively provide for this longitudinal se f-adjustment of the parts.

ment of the bearing ring on the shaft with- The construction illustrated in Fig. 2 is finerally similar to that described except t at in this case the bearing is of the single row t In this construction the inner 11 is.held in longitudinally adjusted 'tion on the 51111 by; abutment collars l s ecured fast to the sha at the opposite ends thereof and provided with longitudinally engaging keying'shoulders 15 and 16 as before described.

In a shaft bearing of this type, particw.

larly where the inner ring isloosely mounted on the. shaft, it is highly important that a long bearing surface be-.provided between.

the ring and shaft to avoid undue strains [upon the inner ring or other parts of the bearing. As shown in the drawing, the 1nner ring 11 is relatively long and one end is extended through the annular dust cap 8 so ."other advantage is that less machine work Qwill be required to form the seat for the 's-outer bearing ring.) The ball races in the rings are preferabl substantially at or near the center of the atter and by having the inner ring extend out through the dust cap. Qtheb'all races ma I hanger box, h

be nearer the end-of the "t erefore less machine work 18 uired for forming the outer ring seat,

' Qf' v provided.

I 'for t e e relative ad ustment of the bearing and shaft, allows for further adjustment of the parts and a a reater distance between two rows M' invention, it will be seen, provides assemblage of the bearing and time to suit conditions and at the of the shaft is taken by roller: elements same time permits of'a limited degree of self-adjustment which is very desirable in bea of the hanger t Furt ermore, it Wlll be noted that in my invention both the radial load and the thrust the balls, friction being thereby reduced to amihimuin.

By the term han er'box as used herein, I do not wish to limit the field of usefulness .ofthe'inventio'n to that of a support for a shaft-onl since the inventionmay be empltiyedy erever found useful. Y 1. In a shaft bearing, the combination with ashaft', of a hairlger box for the same,

outer race rings seate in the op site ends of sand box, inner race loose y engaged on the shaft oggosit'e the outer race rings,

2. In a shaft bearing, the combination outer race rings seate in the op osite ends of said box, inner racerings; loose y engaged on the shaft o posite the outer race rings, roller elements between said inner and outer ere two rows are used maybe tially race rings and abutment collars fixedly engaged on the shaft atthe ends of the inner race rings, and spaced therefrom, the abutting portions of said abutment collars and inner race rings having longitudinally extendin lugs and notches enga ing substanl ongltudinally of the shat whereby to key the race rings on the shaft and at the I same time prov e for limited longitudinal self-adjustment of the bearing elements; 3. In a shaft bearing, the combination with a shaft, of a hanger box for the same,
